To uub whom it may 001mm.-

Be it known that I, C'rmnnns C. R a citizen of Orlando,

nnon'r, the United States, residin at inthe county of Orange and S tate have invented a certain new and useful Improvement in Combined Irrigating and Frost-Protecting Systems, of which. the following is afull', clear, and exact description, reference being had ing drawings.

This invention relates to a system or apparatus which is capable of being used interchangeably for irrigating purposes and for frost-protection purposes.

The general object of the invention is to provide a system .of this kind which is economical of production and which can be quickly and conveniently converted from one urpose to the other and which will be, capable of realizing either of its two functions in an efficient manner.

A further object ofthe invention is to provide a simple, efficient, and improved met-protecting system, irrespective of the irrigating feature. Still further and more limited objects of the invention will appear hereinafter and will be realized in and through the combinations of elements embodied in the claims forming part hereof. ,In the drawings,.Fig. 1 represents a diaamlnatic sectional v1ew of my lllustratin its adaptability. for both irrigating and frost-protecting pur oses; Fig. 2 a detail in sectional elevatlon one of the branch pipes having an irrigating nozzle applied thereto; Fig. 3 a detail in sectional elevation of one of the branch pipes showing the arrangement of the cooperatin parts employed for frost protection; and ig. 4 a planview of the parts shown n Fig. 3.

Describing by reference characters the various parts illustrated herein, 1 denotes an I branch 6 by which it is ordinary pressure pump, the piston of the same being indicated as conventionally driven by a crank disk 2, a link 3, and a connecting rod 4.

Communicating with the suction side of the pump is a supply pipe 5 having a vertical to the accompanywhich are shown as apparatus,

directly connected.

to the ump cylinder. From the delivery end of t e pump there extends a branch pi e 6 and a delivery ipe 7 which is preferab y buried beneath the surface of the ground, for frost rotection, said ipe being rovided. wit vertical branc cs8 exten ing above the ground and provided each with valve 9.

The upper end'of each branch pipe 8 is shown as threaded, and to certain of these branch pipesthere are-a plied irrigating nozzles,-such as shown in ig. 2, each nozzle having a central threaded rtion 10 by which it is mounted upon t e top of the branch pipe. This central connecting ortionconstitutes the bottom of a yoke or branched body 11 having oppositely and upwardly extendihgv passageways 12 therein, the outer ends of-such' passageways communicating with the spray nozzles 13, which may be threaded into said branches and 4 will be used. The nozzles 11 will be re- ,moved, and burners,

7 indicated generally at 15, will be substituted for said nozzles. The burners may be of any approved construction, the one shown herein. having 'each a central sleeve 16 adapted to be threaded upon thcupper end of a branch casing 17 having a central threade 18 carried by spider tarms 19 from of the casing, a burner cap 20 having a stem threaded into the support 18 and ada ted, by its adjustment, to va .the width 0 the annular slot 21 provide between said cap and the to of the burner 15, for the escape; of liquid file]. Thisannular slot 21 may support the wall provided with slots or provided between an outwardly tapered face on the cap 20 and a correspondingly tapered face 15 on the upper end, of the burner casing- 15, so that, when the oil is I forced out through this slot under pressure, it will be discharged in an outwardly and upwardly flaring spray.

For the purpose of protecting each burner and facilitating the combustion of the liquid fuel, hoods are provided, as shown more particularly in Fig. 3. a Each hood comprises a casing 22, preferablyc lindrical and having a partition23 interme iate the top and bottom thereof and in position to coo rate with the top of a branch pipe 8. Eac partition is provided with a central opening for the reception of the upper end of the branch ipe 8 andfor the central sleeve 1t} of a. Burner; In addition, eachpartition is pro- 'vided with openings 24 which are arranged to admit air to the fluid fuel dischargedand sprayed throu hy the slot 21, air being admitted to eac hood below the partition thereof through suitable openings 25.

I An

may be em loyed for supplying oil to the pu p pipe 7 may be used for the supply of 011 to the burners that is used for supplying water .3 to the spray nozzle, it being only necessary to drain the water pipe, or the part thereof e loyed for the conduction of oil.

il may be supplied to the inlet or suction side of the pump 1 by means of a 36 pipe 26 commpnicating at one end with any source of oil su ply and at its other end with the vertical bran'ch 6 of the pipe which normally conducts water to the pump, a suitable valve or valves 27 bein' .emplo ed 40 .toisolate one liquid from the ot er. en .oil is used, a by-pass connection 28 may be inserted between the pipes 6 and 7*, said connection having a check valve 29 therein I which is adapted too 11 and allow the oil to by-pass when a pre etermined pressure is reached in the pipe 7, said check valve being indicated as provided with an ordinary closing screw 29", .to shut the valve when water is being pumped.

to By the system disclosed herein, I am able to conveniently, and at is comparatively small cost, combine irrigation with frost protection, employing a common system of pipe lines for this purpose, and providing means whereby the system ma? be quickly,

conveniently, and economical y from an irrigating system to a heating system, and vice versa; also to rovidea heatng system wherein the liquid fuel may be 00 burned with substantially complete combustion and without the developmentof a I smudge or smoke, which has been found to be objectionable in the treatment of certain crops.

t is contemplated that the same converted Havin thus described my invention, what I c aim is:

1. In a system or apparatus of the character set forth, the combination of a pum a pipe communicating with the inlet si e thereof, a pipe extending from the delivery side thereof and provided with a plurality of branch pipes each havingv a valve therein, said branch pipes having means for securing either burners or spray nozzles there to, means for supplying water and means for supplying fluid fuel to the first-mentioned ipe, and a by-pass connection between t e first and second pi es, said connection having a valve therein adapted to permit circulation from the second pipe to the first pipe upon the development of a predetermined pressure.

2. In a system or ap aratus of the character described, the com ination of a suppl pipe located beneath the soil to be irrigate branch pipes projecting upwardly from said supply pipe and having their endsextend- 7 mg above such soil and provided each with convenient or conventional means a valve, said branch pipes having means for securing either burners or spray nozzles thereto, burner hoods adapted to surround the burners and to rest upon the soil, and means for supplying water and means for supplying fluid fuel through said supply pipe to said branch pipe.

3. A heating system of the character described comprising a supply pipe extending beneath the soil and provided with vertical branches projecting upwardly through such soil, burners connected to and associated with said branch pipes, each burner comprising a liquid spraying or atomizing device and a hood surrounding such device and the upper end of its branch pipe and having a perforated partition located below the spraymg device, the said hood having one or more openings for the admission or air beneath said partition.

4:. A heating system of the character described comprising a supply pipe extending beneath the soil and provided with vertical branches projecting upwardly through such soil, and burners connected to and associated with said branch pipes, and a hood sur rounding each burner and the upperend of its branch pipe and having means for supplying air to such burner.

5. A heating device for the purpose described com'prisinga vertically extending pipe having its upper end provided with a thread, a hood surrounding the said pipe and having a partition provided with a central openin adapted to receive the upper end of tie pipe, and an oil-atomizing device adapted to deliver the oil in an upwardly and outwardly directed spray, the said device having a sleeve extendin' through the opening in said partition an threadedupon the'pipe, the said partition being provided with openings therethrough for the admission of air to said spray and the hood having one or more openings in the wall below said artition.
